What?

• Java is a programming language written once and
  running anywhere and developed by Sun
  Microsystems. It's similar to C and C, but much
  simpler. You can combine Java with many
  technologies like Spring, Node js, Android,
  Hadoop, J2EE, etc. to create powerful, scalable,
  portable and distributed complete applications.
  Java also encourages continuous integration and
  testing with tools like Selenium.

History of Java

• Java was originally developed in the early 1990s
  by James Gosling and his colleagues at Sun
  Microsystems. It was originally called Project
  Oak, which had a similar implementation to C and
  C. The name Java was then chosen after
  considerable brainstorming and was based on the
  name espresso bean. Java 1.0, the first version
  was published in 1995 with the slogan "write
  once, runwhere". Sun Microsystems was later taken
  over by Oracle. From then on there was no turning
  back. The latest version of Java is Java 12 which
  was released in March 2019.

Java Functions

• Java offers many interesting functions -
• Platform independent language
• A comprehensive standard library that makes
  coding easier. You can create complete
  stand-alone applications using Java.
• Java supports automatic memory allocation and
  release (called garbage collection).
• Offers excellent performance as Java supports
  multithreading and concurrency, making it a
  highly interactive and responsive language.
• Safe and easy

When?

• The expansion of the Java programming language is
  very extensive, as evidenced by the claim that 3
  billion devices run Java, which was demonstrated
  during the installation of Java. Java provides a
  rich and extensive set of APIs to help
  programmers develop applications. With the help
  of Java we can develop different applications for
  different purposes. We can use Java technology to
  develop the following applications
• Mobile application development
• Desktop GUI Application
• Web-based application
• Game apps
• Big data technology
• Distributed applications
• Cloud based application
• IoT Applications

Why?

• Java is isolated from other programming languages
  ??in terms of functionality and security and is
  also compliant. There are several other reasons
  to use Java
• Scalability Scalability increases the capacity
  of our system. It increases system capacity by
  adding system resources without affecting the
  deployment architecture. We can achieve
  scalability by increasing resources like RAM and
  CPU in a system. This is important because it
  handles the load, improves system performance,
  and maximizes productivity.
• Cross-platform Cross-platform means that the
  compiled Java program can run on all platforms.
  Remember that the system must have a JVM. After a
  Java program is compiled, the Java code is
  converted into platform-independent byte code.
  This bytecode is understood by the JVM. We can
  run this bytecode on any platform.
• Memory management Java has its own memory
  management mechanism known as garbage collection.
  We don't have to worry about storage and we don't
  have to implement it to manage storage. It
  automatically deletes objects when they are no
  longer used by the application. Increase
  application speed.
• Multithreading Threads are lightweight
  sub-processes. Multithreading in Java allows two
  or more threads to run at the same time. This
  maximizes CPU usage.

Conclusion

• Java is multithreaded, meaning multiple tasks can
  be handled simultaneously and users can construct
  interactive applications that run smoothly. With
  its secure features, virus-free, tamper-free
  systems can be developed. Authentication
  techniques are based on public-key encryption.
